keep in mind that any number to the power 0 is equal to 1 therefore if you check carefully in the expression you will find that [tex](b^{5} c^{4} )^{0} =1[/tex]
And you should be able to know and apply the rules of exponents
but in this case the only one to be applied is :if you are to are multiplying powers of the same base add the exponents.
